Cavity Insulation Archives

Domestic and commercial buildings constructed after the 1930s typically have cavity walls – two layers of brickwork with a gap in between. Without proper insulation, heat can escape through this gap. Hence, cavity wall insulation is required to trap heat, significantly improve energy efficiency, and reduce heating bills.

Building Shop offers a comprehensive range of insulation materials suitable for partial or full cavity wall filling. Choose from durable cavity batts and rolls made from glass mineral wool or versatile PIR (polyisocyanurate) boards, which are also ideal for insulating pitched roofs and floors. Additionally, we stock specialist cavity closers from leading brands like Kingspan, which are perfect for sealing gaps around windows and doors.
